A senior Iranian commander called on the country's Air Force officials to keep more vigilant about the plots hatched by the enemies to collect information and intelligence on the country's military sites and equipment.

"The arrogant powers are attempting to collect intelligence on Iran's military with the help of the terrorist Mojahedin-e Khalq Organization (MKO also known as the MEK, PMOI and NCR)," Air Force Deputy Commander for Coordination Brigadier General Aziz Nasirzadeh said on Sunday.

"To confront the enemy's traps, we should act very vigilantly and carefully because sometimes the smallest mistake has irreparable effects," he added.

Nasirzadeh's remarks came after the US removed the MKO from the country's list of terrorist groups, which he called as the enemy's new trick to pursue its ominous goals against the Iranian nation.

Late in September 2012, the US State Department removed the MKO from its list of foreign terrorist organizations. The decision made by former Secretary of State Hillary Clinton enabled the group to have its assets under US jurisdiction unfrozen and do business with American entities, the State Department said in a statement at the time.
